Elid superfinishing of spherical bearings [PDF]

open access: yes, 2007
Driven by a requirement to extend the lifespan of self-aligning lined spherical bearings, this research investigates the use of Elid (electrolytic in-process dressing) as a method of improving ball surface finish.

The effects of lapping load in finishing advanced ceramic balls on a novel eccentric lapping machine [PDF]

open access: yes, 2005
HIPed (Hot Isostatically Pressed) silicon nitride ball blanks were lapped from diameter 13.255 mm to diameter 12.7 mm by a novel eccentric lapping machine. A maximum material removal rate of 68 μm/hour has been achieved under a nominal lapping load of 43

Parameter optimization by Taguchi Methods for finishing advanced ceramic balls using a novel eccentric lapping machine [PDF]

open access: yes, 2001
The final finishing process of advanced ceramic balls used in hybrid precision bearings constitutes two-thirds of the total manufacturing cost, and hence effective and economic finishing methods and processes are critical to their widespread application.

The polishing process of advanced ceramic balls using a novel eccentric lapping machine [PDF]

open access: yes, 2005
The finishing process of advanced ceramic balls can be divided into two steps. The first step is lapping in which most of the stock from the ball is removed at a higher material removal rate.

Finishing of Cylindrical Surfaces by Using Lapping Films.

open access: yesJournal of the Japan Society for Precision Engineering, 1992
Many types of lapping films are manufactured today. This is because they greatly improve the finishing process and reduce the finishing costs. However, the effects of the structural characteristics of lapping films and the elastic contact conditions between contact roll and workpiece on the performance of finishing have not yet been fully explained. In

Study on Precision Cylindrical Lapping : on the Condition for Modification of Roundness Error

open access: yesBulletin of JSME, 1983
This paper discusses analytically on the condition for modification of the work roundness error and improvement to the value of about 0.1 μm by a simple conventional cylindrical lapping method, considering that it has been very difficult to machine a cylindrical workpiece at its top position supported with two free rotating rollers. The analysis points
